TXT-tool 4.034-1.1: Quantitative Rockfall Risk Assessment for Roadways and Railways
This tool presents a methodology for quantifying the rockfall risk and the consequences for vehicles circulating on roadways and railways. We present a complete and comprehensive methodology for risk assessment, using various risk descriptors, with an emphasis on the quantification of the exposure of the vehicles and the consequences from rockfall hits, in function of the rockfall frequency and magnitude. Indications on the calculation of the repair costs for damaged roadways and railways and for the indirect loss, due to their temporary closure, are also given. This methodology is useful for end-users involved in the risk management and the design of protection measures.
